Dockable Billboards For Labeling Objects In A Display Having A Three-Dimensional Perspective Of A Virtual or Real Environment

ABSTRACT

A system and method that allows a user to view objects in a three-dimensional environment, where one or more of the objects have a data display (e.g., a data billboard, etc.) that shows data about the object. To enhance user experience and to provide relevant contextual data as the user navigates through the three-dimensional environment, the system calculates a location for the user and a location for each object and determines if a relationship between the user frame of reference and each object location satisfies a first criterion. If the first criterion is satisfied, the system is configured to move the data display to the bottom of a viewing area of the three-dimensional environment (e.g. docking the data display to the bottom of the viewing area, etc.). The system may also arrange the data displays in the same order as the objects are perceived by the user in the three-dimensional environment.

TECHNOLOGY

The present invention relates generally to information systems, and inparticular, to extracting and viewing data generated by informationsystems.

BACKGROUND

Information systems generate vast amounts of information that can bedifficult to view and from which it can be difficult to extract usefulinsight. Although the development of computers and software has beenstaggering in many ways, existing computer systems are still limited intheir capacity to convey large amounts of data in a way that users candigest and understand quickly. Because the amount of relevant data thatis available for analysis continues to increase significantly from yearto year, the need for improved tools for communicating such data tousers is becoming urgent.

The approaches described in this section are approaches that could bepursued, but not necessarily approaches that have been previouslyconceived or pursued. Therefore, unless otherwise indicated, it shouldnot be assumed that any of the approaches described in this sectionqualify as prior art merely by virtue of their inclusion in thissection. Similarly, issues identified with respect to one or moreapproaches should not assume to have been recognized in any prior art onthe basis of this section, unless otherwise indicated.

1. General Overview

This overview presents a basic description of some aspects ofembodiment(s) of the present invention. It should be noted that thisoverview is not an extensive or exhaustive summary of aspects of theembodiment. Moreover, it should be noted that this overview is notintended to be understood as identifying any particularly significantaspects or elements of the embodiment(s), nor as delineating any scopeof the embodiment(s) in particular, nor the invention in general. Thisoverview merely presents some concepts that relate to exampleembodiments in a condensed and simplified format, and should beunderstood as merely a conceptual prelude to a more detailed descriptionof example embodiments that follows below.

In various embodiments, a system and method is provided that allows auser to view objects in a three-dimensional environment (e.g., a 3Dspace, a 3D spatial region, etc.) with a display (e.g., a wearabledisplay, on a two or three-dimensional display, or on any other suitabledisplay, etc.), where one or more of the objects have a data display(e.g., a billboard, etc.) associated with the object that shows dataabout the object. In various embodiments, the data display containsreal-time streaming textual data about the object. To enhance the userexperience as the user navigates through the three-dimensionalenvironment, the system calculates a location of the user and a locationfor at least one object. The system then determines a distance betweenthe user and the at least one object. If the distance between thelocation of the user and the at least one object is within apredetermined distance, the system may be configured to move the datadisplay for the at least one object to a designated area (e.g., awayfrom the at least one object, etc.) such as the bottom of a viewing area(which may be a part or the entire display area of a display/screen of acomputing device) of the three-dimensional environment (e.g., dockingthe data display at the bottom of the viewing area). When more than onedata display is docked at the bottom of the viewing area, the system maybe configured to arrange the data displays in the same order as theobjects are perceived by or displayed to the user.

In some embodiments, the three-dimensional environment is a computergenerated virtual environment. The three-dimensional environment can beviewed by the user on a two-dimensional or three-dimensional displayfrom the perspective of a virtual camera that is positioned in theenvironment. Thus, a displayed view of the three-dimensional environmentshown on the display is determined by the location and the perspectiveof the virtual camera. As the user navigates through the virtualenvironment (e.g., moves the location of the virtual camera in thevirtual environment, etc.), for example by using a joystick, acontroller, a mouse, a keyboard, or any other suitable method ofcontrolling the location and direction of the virtual camera, the datadisplays may be docked or undocked at the bottom of the viewing area,and/or arranged based on the arrangement of the objects in displayedviews of the three-dimensional environment as perceived from the virtualcamera. Docking of the data displays may be carried out when thelocation of an object with respect to the location of the virtual camerasatisfies a data display docking criterion (e.g., the distance betweenthe object and virtual camera is less than a threshold distance, theobject is located within a predetermined radius from the location of thevirtual camera, any other suitable criterion, etc.). Additionally,optionally or alternatively, the data display docking criterion is basedat least in part on a function, algorithm, etc., that depends on one ormore of (a) a distance of a three-dimensional object relative to theuser's location as represented in the three-dimensional environment, and(b) an angle between (1) a first imaginary line connecting athree-dimensional object (e.g., the central location of thethree-dimensional object, etc.) and the user's location, and (2) asecond imaginary line representing the user's perspective. Additionally,optionally or alternatively, a user or a system can specificallydesignate/configure a three-dimensional object to have its correspondingdata display to be docked in a designated area of a view of thethree-dimensional environment; for example, the configurable designationof the three-dimensional object to have its corresponding data displayto be docked may be included as a part of the data docking criteria.

In various other embodiments where the three-dimensional environment isa superimposition of (1) a computer-generated three dimensionalenvironment that comprises graphic objects, data displays, etc., and (2)a real-world environment that surrounds the user, the three-dimensionalenvironment may be viewed by the user through a wearable display such asa heads-up display, display glasses, etc., which includes, but is notlimited to only, a display attached to a wearable computer that isimaging the real-world environment in real-time as the user movesaround. In these embodiments, the system may receive real-time data,non-real-time data, etc., about objects in the surrounding environmentand overlay/superimpose at least a portion of the data on the objectsviewed by the user or imaged by a camera. For example, if a user iswearing GOOGLE GLASSES®, the user can walk through New York City andview the buildings, shops, and other objects surrounding the user as theuser walks down 5th Avenue. Based on position and location informationdetermined by the GOOGLE GLASSES® using various sensors (e.g., GPS,motion sensors, head-tracking sensors, etc.), the system may downloadinformation about the various buildings, shops, and landmarks (e.g.,objects, etc.) and display the information on data displays (e.g., abillboard, etc.) associated with the object(s) viewed by the user. Thus,as the user navigates down 5th Avenue, the system can move (e.g., dock,etc.) various billboards for objects that satisfy a criterion (e.g., theobject is within a threshold distance from the user, etc.) to the bottomof the viewing area (as defined by the heads-up display or display) inthe glasses. This allows the user to focus on billboards for objectsthat are relevant to the position of the user in the user's surroundingenvironment. In some embodiments, while a user is walking in areal-world environment, a wearable computing device may render 2D and 3Ddisplayed graphic objects (e.g., undocked billboards, markers, shapes,maps, etc.) at specific coordinates (e.g., x-y-z coordinates of a spacerepresenting the user's real environment, etc.) of the user's real-worldenvironment, for example, as if the 2D and 3D graphic objects, etc., area part of the user's real-world environment.

In still other embodiments where the three-dimensional environment is athree-dimensional interactive map (e.g., APPLE® 3D with navigationfunctionality, etc.) a user may view a map of an area on a handhelddevice, a tablet or any other display device. As the user navigatesthrough the map, the system may be configured to overlay data billboardson one or more of the objects (e.g., buildings, landmarks, monuments,restaurants, etc.) in the displayed view to provide the user withrelevant data associated with the objects. In this way and similar tothe embodiments described above, as the virtual camera viewpoint ismoved through the 3D map, the user can see information about buildings,landmarks, monuments, retail establishments and any other objects beingdisplayed to the user. Additionally, the data displays for objectswithin a predefined proximity to the virtual camera location may bedocked at the bottom of the display so that relevant information aboutone or more objects within the predefined proximity can be easily viewedby the user.

Various modifications to the preferred embodiments and the genericprinciples and features described herein will be readily apparent tothose skilled in the art. Thus, the disclosure is not intended to belimited to the embodiments shown, but is to be accorded the widest scopeconsistent with the principles and features described herein.

Accordingly, variousembodiments may be entirely hardware or a combination of hardware andsoftware. Furthermore, particular embodiments may take the form of acomputer program product stored on a computer-readable storage mediumhaving computer-readable instructions (e.g., software, etc.) embodied inthe storage medium. Various embodiments may also take the form ofinternet-based computer software and/or hardware. Any suitablecomputer-readable storage medium may be utilized including, for example,hard disks, compact disks, DVDs, optical storage devices, and/ormagnetic storage devices.

Various embodiments are described below with reference to block diagramsand flowchart illustrations of methods, apparatuses (e.g., systems,etc.), and computer program products. It should be understood that eachblock of the block diagrams and flowchart illustrations, andcombinations of blocks in the block diagrams and flowchartillustrations, respectively, can be implemented by a computer executingcomputer program instructions. These computer program instructions maybe loaded onto a general purpose computer, a special purpose computer,or other programmable data processing apparatus to produce a machine. Assuch, the instructions which execute on the general purpose computer,special purpose computer, or other programmable data processingapparatus can direct a computer or other programmable data processingapparatus to function in a particular manner such that the instructionsstored in the computer-readable memory produce an article of manufacturethat is configured for implementing the functions specified in theflowchart block or blocks. The program code may execute entirely on theuser's computer, partly on the user's computer, as a stand-alonesoftware package, partly on the user's computer and partly on a remotecomputer, or entirely on the remote computer or server. In the latterscenario, the remote computer may be connected to the user's computerthrough any type of network, including: a local area network (LAN); awide area network (WAN); a cellular network; or the connection may bemade to an external computer (for example, through the Internet using anInternet Service Provider).

FIG. 1 shows a block diagram illustrating an example data display systemfor displaying dockable billboards for labeling objects in athree-dimensional display of a virtual or real environment. The systemcomprises a server (or computing device) 115 that communicates with aplurality of data sources 105 and a plurality of client devices 140 overa network 110 (e.g., the Internet, a cellular network, Wi-Fi, etc.). Forthe purpose of illustration only, as depicted in FIG. 1, a dockable datadisplay module 120 is included in server 115. However, it should benoted that in various embodiments, one or more dockable data displaymodules (e.g., 120, etc.) may be located in one or more of clients(e.g., client device 140, etc.), servers (e.g., 115, etc.), etc. Forexample, a client device (e.g., 140, etc.) can comprise a dockable datadisplay module configured to communicate with a plurality of datasources 105 over network 110.

In various embodiments, the data sources 105 may include any source ofdata that is relevant to objects in the three-dimensional environment orreal-world environment. For example, data source 105 may includecomputers, routers, databases, operating systems, applications, mapdata, Internet data or any other source of data. For example, in variousembodiments where one or more data sources are computers, each datasource 105 may produce one or more different types of machine data (e.g.structured data, unstructured data, unparsed data, server logs, activitylogs, configuration files, messages, database records, and the like). Inother embodiments where a data source 105 provides map data, one datasource may supply 3-dimensional, interactive map data while another datasource 105 may supply information about various objects located withinthe map.

In various embodiments, the server may receive data from data sources105 over network 110 in real-time, which may be stored in random accessmemory but not stored locally at server 115. In other embodiments, theserver 115 may receive the data from the data sources 105 and store thedata locally at server 115, for later use. In these embodiments, thedata and three-dimensional environment may be transmitted from server115 to one or more of the client devices 140 for viewing by a user. Instill other embodiments, the data may be transmitted from the server 115to the client device where it is either immediately viewed or storedlocally for later use.

3. Second Exemplary Data Display System

FIG. 2 shows a perspective view of a wearable computer 200 (e.g., aclient device 140 of FIG. 1, etc.) with an optical head mounted display202 coupled to a frame 204 having first and second temples 206 and 208and nose supports 210. The wearable computer 200 displays information ina smartphone like, hands-free format that can interact with the Internetand other application via natural language voice commands. The wearablecomputer 200 has a camera 212 that is capable of taking photos andrecording video. The wearable computer may contain various sensorsincluding, but not limited to, gyroscopes, accelerometers,magnetometers, ambient light and proximity sensors, geosynchronouspositioning sensors, a geomagnetic field sensor, an orientation sensorand gravity sensors (further described with reference to FIG. 3), etc.The wearable computer may also have one or more of a Wi-Fi transceiver,a Bluetooth transceiver, a cellular transceiver (or a single device thatfunctions as all of these communication devices), storage memory, randomaccess memory, a processor (further described with reference to FIG. 3),etc., which may be contained in one of the housings 214 a and 214 b. Invarious embodiments, the wearable computer may contain one or moreheads-up displays—instead of or in addition to the optical display202—that is mounted adjacent to, or unitarily formed with lenses mountedin frame 204. The one or more heads-up displays allow the wearer (oruser) to view a scene in the surrounding environment where data, eitherstored in memory or streamed real-time, to the wearable computer isprojected on the one or more heads-up displays so as to align with,superimpose/overlay or be linked to, at least one object viewed by theuser.

In various embodiments, the wearable computer 200 may take the form ofremovable modular housings 214 a and 214 b that couple to the frame 204.The housings 214 a and 214 b may be removably secured to a temple (e.g.,the temple 206, etc.) of the frame 204. In other embodiments, thewearable computer 200 may be integrally formed with the frame 204. Frame204 may include a pair of lens openings (not shown) for mountingprescription or non-prescription lenses. In other embodiments as shownin FIG. 2, no lens openings are present. The lens openings may define anoptical path for a user wearing the frame 204.

FIG. 3 is a block diagram illustrating the components of the wearablecomputer shown in FIG. 2. One of the housings 214 a and 214 b maycontain and/or support a circuit 216, a speaker 218 for providing soundto the user, a microphone 220 for receiving voice commands or speechfrom the user, a haptic device 222 for providing input to the user, abone conduction device 224 for providing vibration to the user, and atleast two accelerometers 226 a-226 b that are used by the electronics/RFcircuit 216 to receive inputs from the user. Furthermore, one of thehousings 214 a and 214 b may also contain one or more batteries 228 thatprovide power to the circuit 216. The one or more batteries 228 may beremovably or permanently disposed within the one of the housings 214 aand 214 b.

The circuit 216 comprises a processor 236, a transceiver 238, memory240, a display driver 242 and a temperature sensor 244. The transceiver238 may be configured to send and receive cellular signals, Bluetoothsignals, Wi-Fi signals and geosynchronous signals via an antenna 246 tothe other external devices 234. In various embodiments, applications,modules, data and other information may be stored in the memory 240.

The accelerometer 226 a may be oriented to sense a pitch movement of theframe 204 (e.g., a movement of the user's head, etc.) about a pitch (orhorizontal) axis. The pitch axis may be defined from left to rightthrough the frame 204. The second accelerometer 226 b may be oriented tosense a yaw movement of the frame 204 (e.g., a movement of the user'shead, etc.) about a yaw (or vertical) axis. The yaw axis may be definedas a vertical (relative to the ground) axis through the frame 204.

As a result, each of the accelerometers 226 a and 226 b may beoperational to sense and report a direction of acceleration. Forexample, the pitch accelerometer 228 a may generate a positive value inresponse to a forward rotation (e.g., user's nose moving down, etc.) ofthe frame 204 about the pitch axis. A negative value may be generated inresponse to a backwards rotation (e.g., user's nose moving upwards,etc.) of the frame 204 about the pitch axis. Likewise, the yawaccelerometer 226 b may generate a positive value for a clockwiserotation of the frame 204 (e.g., user's left ear forward, right earbackwards, etc.) about the yaw axis. A negative value may be generatedfor a counterclockwise rotation of the frame (e.g., user's left earbackwards, right ear forward, etc.) about the yaw axis. Thus, an outputsignal from the pitch accelerometer 226 a may be used to answer atelephone call in response to the accelerometer 226 a detecting anodding “yes” (pitch) movement of the user's head. A shaking “no” (yaw)movement of the user's head may cause the second accelerometer 226 b tosend a different command to circuit 216 to not answer the call.

The circuit 216 may be configured to provide two-way radiocommunications with other external devices 234 (e.g., other phones,computers, etc.). For example the electronics/RF circuit 216 may receivetelephone calls or display data on the display 202. The commandsprovided to the wearable computer 200 may be generated in a hands-freemanner (e.g., without a user pressing a button with his or her hands,etc.). The communications may be implemented using a wireless Bluetoothstandard, a wireless Universal Serial Bus (USB) standard, a cellulartelephone standard, a Wi-Fi standard, etc. Other standard and/orpropriety protocols may be implemented to meet the criteria of aparticular application.

4. Exemplary Data Display Method

The system of FIG. 1 or the wearable computer of FIG. 2 may beconfigured to perform the method steps of FIG. 4. Moreover, the methoddescribed in FIG. 4 is an example of an embodiment of present methodsfor displaying dockable billboards for labeling objects in athree-dimensional display of a virtual or real environment. It should beunderstood by reference to this disclosure that the method describes anexample embodiment of the methods steps carried out by the presentsystem, and that other example embodiments may be created by addingother steps or by removing one or more of the method steps described inFIG. 4.

FIG. 4 depicts an example method for displaying dockable billboards forlabeling objects in a two-dimensional or three-dimensional display of a(e.g., a navigable, etc.) virtual and/or real three-dimensionalenvironment. The method begins at step 300 when the system determines alocation and a camera viewpoint of a virtual camera positioned in thethree-dimensional environment. In various embodiments, the cameraviewpoint of the virtual camera may represent a perspective of a userrepresented at the location in the three-dimensional environment, andthe location of the virtual camera may be the same as the user'slocation as the user is being represented in the three-dimensionalenvironment. In some embodiments, the location and camera viewpoint ofthe virtual camera can be determined by the physical location andorientation as detected by one or more sensors (e.g., motion sensors,location sensors, orientation detection sensors, accelerometers,magnetic sensors, GPS sensors, etc.) worn by a user as the usernavigates around the user's environment. For example, in variousembodiments having a wearable computer attached to the user's head(e.g., via spectacle frames, etc.), a scene captured by the wearablecomputer may be displayed on a display coupled to the wearable computerso that the user can view a scene of the surrounding environment withdata billboards linked to, or overlaid on, at least one of the objectsbeing viewed in the environment. Thus, in this example, the position,location, orientation, motion, etc., of the wearable computer, asdetermined by various sensors attached to the wearable computer, may beused to obtain data associated with the viewed objects. Continuing withthis example, the data associated with the objects may be, but is notlimited only to, real-time streaming data (e.g., data obtained over acellular data connection, a Wi-Fi connection or a Bluetooth connection,etc.) or the data may be stored in memory that is part of the wearablecomputer.

At step 302, the system 100 or system 200 may be configured to determinea distance between the camera (virtual camera) location and at least oneobject located in the environment. In various embodiments, the virtualcamera location and the location of at least one object may becalculated based on a common coordinate system (e.g., Cartesian, polar,etc.) for the virtual environment. In other embodiments that use awearable computer, the location of the virtual camera may be determinedusing geosynchronous information that is received by the wearablecomputer, and the location of each object in the three-dimensionalenvironment may be calculated with respect to the location of thewearable computer based on a known longitudinal and latitudinal positionof each object.

At step 304, the system 100 or wearable computer 200 determines whethera location for the object with respect to the location of the camera(virtual camera) viewpoint satisfies a first criterion (e.g., a datadisplay docking criterion, etc.). In various embodiments, the firstcriterion may be the proximity of the object to the location of thevirtual camera (e.g., the location of the user as represented in thethree-dimensional environment, etc.), where the first criterion issatisfied by a set number of objects that are closest to the location ofthe virtual camera. In other embodiments, the first criterion may be athreshold distance, where the first criterion is satisfied when thedistance between the location of an object (e.g., all-around, in frontof the virtual camera, etc.) and the location of the camera itself iswithin the threshold distance. In still other embodiments, the firstcriterion may be a predefined radius around the location of the camera(virtual camera), where the first criterion is satisfied if an objectlocation is within the predefined radius. It should be understood inlight of this disclosure that there are many ways to determine thedistance between an object in a three-dimensional environment and acamera (virtual camera) represented in the three-dimensionalenvironment, and all such methods are contemplated by the presentdisclosure.

If an object location, with respect to the location of the camera(virtual camera) satisfies the first criterion, at step 306, the system100 or wearable computer 200 moves a data billboard for the object to apredetermined location in (or a designated portion of) a viewing area(which may be a part or the entire display area of a display/screen of acomputing device) of the three-dimensional environment. Thepredetermined location may be any location where one or more datadisplays may be grouped for the objects that satisfy the firstcriterion. In various embodiments, the predetermined location of theviewing area may be away from the object to which the billboardcorresponds, proximate to a specific designated location, or in adesignated area such as an area along a bottom edge, a left edge, topedge, right edge, etc., of the viewing area. In one or more embodiments,the predetermined location may be top or side edge of the viewing area.

It should be understood from reference to this disclosure that invarious embodiments, the viewing area corresponds to a scene (e.g., adisplayed view, etc.) of the three-dimensional environment that would becaptured from a viewpoint positioned at the location and the perspectiveof the virtual camera. If a data billboard for an object is alreadylocated at the predetermined location in the viewing area, in variousembodiments, the system maintains the position of the data billboard atthe predetermined location (e.g., keeps the billboard docked at thebottom of the viewing area, etc.). In various embodiments, when the databillboard is moved to the predetermined location, it may be linked toits corresponding object using a lead line (e.g. a solid or dotted line,etc.). In some embodiments, solid lines may be used to link a billboardto an object that can be seen from the camera viewpoint and dotted linesmay be used to link billboards to objects that are located behindanother object and not in the line of sight, in displayed views of thethree-dimensional environment as perceived from the camera viewpoint. Instill other embodiments, the data billboard may be colored to match acolor of its corresponding object. In still other embodiments, theobject may be marked with a marker (e.g., a shaped marker, an encirclednumber, etc.) and the data billboard may contain or be associated with acorresponding marker thereby allowing the user to link each docked databillboard with its corresponding object.

In embodiments using a wearable computer having a camera, the viewingarea (the displayed view as rendered on the display with the user) ofthe three-dimensional environment is a scene that is captured by thecamera. In still other embodiments that use a heads-up display (e.g., atransparent display associated with a wearable computer, etc.), theviewing area (the displayed view as rendered on the display with theuser) of the three-dimensional environment corresponds to that portionof the real-world environment that may be viewed by the user through theheads-up display or through the transparent display. In theseembodiments, moving the data billboard to a designated area of theviewing area such as a bottom edge, etc., of the viewing area furthercomprises moving the data billboards for those objects that satisfy thefirst criterion to a bottom edge of the heads-up display, the bottomedge of the transparent display or a bottom edge of a two-dimensionaldisplay that displays the viewing area of the three-dimensionalenvironment (which may overlaid or superimposed with a portion of thereal-world three-dimensional environment in some embodiments).

In various embodiments, each data billboard is arranged in thedesignated area so that the data billboards do not overlap with oneanother. This allows the user to read the content of each of the databillboards. In some of these embodiments, the data displays (e.g.,billboards docked or moved into the predetermined location, thedesignated area, etc.) may be presented in the same order as the orderof the objects—from which the data displays were moved into their dockedposition in the predetermined location, the designated area, etc.—indisplayed views of the three-dimensional environment as perceived fromthe location and the perspective of the camera (virtual camera), forexample, about the yaw angle (e.g., horizontally, etc.). In still otherembodiments, at step 308, as the perspective of the camera pans (e.g.,the yaw angle changes, etc.) across the three-dimensional environment,the data billboards for objects that satisfy the first criterion aredynamically rearranged based on lateral changes in the relativepositions of the objects in displayed views of the three-dimensionalenvironment, as perceived by the camera (virtual camera), etc. Themethod then restarts at step 300.

If, on the other hand, a location of an object with respect to thelocation of the camera (virtual camera) viewpoint fails to satisfy thefirst criterion, at step 310, the system 100 or the wearable computer200 removes the data display if docked at the particular location in theviewing area back to the object, or if the data billboard was notdocked, the system maintains the data billboard near or on itscorresponding object. At step 310 the system may rearrange the existingdocked billboards in accordance with at least a second criterion. Thesecond criterion can, but is not limited to, a docked display orderingcriterion that orders lateral positions of data billboards in the sameorder as the order of objects to which the data bill boards correspondin displayed views of the three dimensional environment as perceivedfrom the location and the perspective of the virtual camera. Once thedocked data billboards are rearranged, the method then restarts at step300.

In various embodiments, in response to receiving (e.g., user, system,etc.) input specifying that the camera (virtual camera) changes from afirst location to a second location and/or from a first perspective to asecond perspective, the system dynamically moves each data billboardfrom the predetermined location in the predetermined location,designated area, etc. of the viewing area (e.g., undocks the billboard,etc.) back to an undocked position (e.g., overlaid on an object oradjacent the object to which the data billboard corresponds, etc.) oncethe object corresponding to the data billboard fails to satisfy thefirst criterion. Furthermore, the system dynamically moves eachbillboard for its corresponding object from a position on, or adjacentto, the object to the predetermined location, designated area, etc., inthe viewing area (e.g., docks a data display, etc.) once the objectcorresponding to the billboard satisfies the first criterion. Moreover,in various embodiments, the system may be configured to rearrange thedocked billboards as the camera (virtual camera) viewpoint moves fromthe first location to the second location based on at least a secondcriterion. In some embodiments, the second criterion may be the relativelocation of each object with respect to the other objects in displayedviews of the three-dimensional environment as perceived from the camera(virtual camera).

5. Example User Experiences

The operation of example embodiments of the present system and methodsare perhaps best understood by reviewing particular examples. Thefollowing examples describe the experience of the user while using thedata display system of FIG. 1 or the wearable computer of FIG. 2. In theexamples described herein, the three-dimensional environment is shown ona two-dimensional display that is viewed by the user. However, it shouldbe understood from reference to this disclosure that when using thewearable computer, the real-world environment may be viewed by the userthrough a heads-up display that overlays the billboards associated withobjects onto the viewed scene in a manner that links each billboard toits corresponding object. Thus, in embodiments that use a heads-updisplay, the term heads-up display should be understood to includeinstances where the data billboards are projected onto the lenses ofglasses, or the lenses of the glasses are configured to operate as atransparent display so that the billboards are overlaid onto the scenebeing viewed by the user through the transparent display. Additionally,the data billboards may be directly projected onto the retinas of theuser so that the billboards are perceived by the user as being projectedinto the environment.

6. First Example User Experience

Referring to FIG. 5 through FIG. 8, a three-dimensional environment isshown having one or more objects 402-412 located therein. Referringparticularly to FIG. 5, at least one of the objects has a data display(e.g., data billboard, etc.) 414, 416, 418, 422, and 424 located on itscorresponding object. In the example shown, each object corresponds to aprocessor in a multi-processor environment (e.g., a server farm, etc.).Thus, the dimensions of the object correspond to a facet of dataassociated with the processor. In various embodiments, the data displays414, 416, 418, 422, and 424 display real-time textual data associatedwith the corresponding object (e.g., processor, etc.). Referring to FIG.6, as the camera (e.g., virtual camera, a user represented by thethree-dimensional environment, etc.) moves from an initial location andan initial perspective corresponding to the displayed view shown in FIG.5 to a first location and a first perspective corresponding to thedisplayed view shown in FIG. 6, the object 402 moves within a particularproximity (e.g., satisfying a first criterion as previously discussed,etc.) with respect to the camera causing the data billboard to move(e.g., dock, etc.) to the predetermined location 426 (e.g., a designatedarea, etc.) in a viewing area 428 (e.g., a displayed view, etc.) of thevirtual environment 400. That is, the viewing area 428 is that portionof the scene of the (e.g., virtual, etc.) three-dimensional environment400 that is perceived by a virtual camera with the first location andthe first perspective in the (e.g., virtual, etc.) three-dimensionalenvironment. In some embodiments, a data display (or a data display areathereof) that corresponds to (e.g., associated with, etc.) athree-dimensional object displays the same content when the data displayis undocked (e.g., located at a position aligned with the position ofthe three-dimensional object in displayed views of the three-dimensionalenvironment, etc.) and when the data display is docked in apredetermined location (e.g., a designated area not aligned with theposition of the three-dimensional object, etc.). A data display asdescribed herein can be used to display textual data as well asnon-textual data. For example, a data display may be used to displaygraphic data, map data, topological data, topographic data, actionablecontrols (e.g., a user selectable control to perform an operation or anaction, etc.), etc. In some embodiments, a data display is interactivein that a user can perform user interaction, perform user input, etc.,with respect to the data display or displayed components therein. Forexample, a user may be presented with high-level depiction of abuilding, a system, etc., initially in a data display; the user canselect an object portrayed in the high-level depiction to find detailedinformation, detailed sub-components, etc., in a component representedby the selected object.

Referring to FIG. 7, when the camera viewpoint moves from the firstlocation and the first perspective to a second location and a secondperspective in the three-dimensional environment, the viewing area 430of the three-dimensional environment, as perceived from the camera atthe second location with the second perspective, changes as illustratedin the figure. As such, object 402 remains within the particularproximity (e.g., satisfying a first criterion as previously discussed,etc.) with respect to the camera at the second location with the secondperspective (e.g., the billboard 414 remains docked, etc.) but otherobjects 404, 405, 406 and 410 move within the particular proximity withrespect to the camera at the second location with the secondperspective. Thus, the billboards 416, 418 and 422 dock in thepredetermined location 426 (e.g., the designated area, etc.) innon-overlapping positions. In some embodiments, the billboards 416, 418and 422 as docked are arranged in the same order as the order of lateralpositions of the objects to which the billboards 416, 418 and 422respectively correspond in the (e.g., currently, etc.) displayed view ofthe three-dimensional environment (or the viewing area), as perceivedfrom the camera at the second location with the second perspective.Because object 412 remains outside the particular proximity (e.g., notsatisfying the first criterion, etc.) with respect to the camera at thesecond location with the second perspective, billboard 424,corresponding to object 412, remains undocked and positioned on theobject 412.

Referring to the upper viewing area 432 in FIG. 8, as perceived from thecamera (or virtual camera) at a third location with a third perspective,multiple billboards 412, 414, 416, 418, 420, 422, and 424 are docked atthe predetermined location 426 (e.g., in the designated area, etc.) inviewing area 432. That is, with respect to the third location and thethird perspective, each of the objects 402, 405, 406, 408, 410 and 412are located at a distance within the particular proximity from thecamera at the third location with the third perspective such that eachcorresponding billboard 414, 416, 418, 47, 420, 422 and 424 is docked atthe predetermined location 426 (e.g., in the designated area, etc.) ofthe viewing area 432. Moreover, each docked billboard is arrangedaccording to the relative lateral position of its corresponding objectwith respect to the other objects, as perceived from the camera at thethird location with the third perspective.

Referring to the lower viewing area 434, as perceived from the camera(or virtual camera) when the camera is moved to a fourth location and afourth perspective, all of the same objects shown in the upper viewingarea 432 are still within the particular proximity to the camera at thefourth location with the fourth perspective. Thus, all of the dockedbillboards remain docked. However, in the viewing area 434 as perceivedfrom the camera at the fourth location with the fourth perspective, thelateral position of each object has changed with respect to the otherobjects. As a result, billboards 417 and 418 are dynamically reordered,and billboards 422 and 424 are dynamically reordered as the camera movedfrom the third location and the third perspective to the fourth locationand the fourth perspective.

In all of the viewing areas shown in FIG. 5 through FIG. 8, the datapresented on the billboards may be real-time textual data, non-real-timetextual data, etc., associated with a processor that corresponds to theobject associated with the respective billboard.

7. Second Example User Experience

FIG. 9 and FIG. 10 illustrate a three-dimensional environment 436 havingone or more objects 438-448 located therein. In the particularembodiment shown in FIG. 9 and FIG. 10, the three-dimensionalenvironment is being viewed using a wearable computer or directly by theuser through a heads-up display. In some embodiments, the user may bewearing a computer coupled to a camera where images captured by thecamera of the real-world environment surrounding the user are viewed ona two-dimensional display. In some embodiments, the user may be viewingthe real-world environment surrounding the user through a transparentheads-up display or transparent display where billboards containing dataassociated with the objects being viewed are overlaid or linked to theobjects. For example, the real-world environment may be a town or city(e.g., New York City, etc.) and the objects in the user's view may be aretail store (e.g., a coffee shop, a building supply store, etc.), aservice provider (e.g., a doctor, a dentist, etc.), etc., that may belocated in one or more buildings. The objects being viewed in thereal-world environment may also be a landmark (e.g., the Empire Statebuilding, a museum, a monument, etc.).

Referring particularly to FIG. 9, a user (with which a camera or virtualcamera is collocated and shares the same location and perspective) isstanding on 5th avenue 450 in New York City wearing the wearablecomputer of FIG. 2. At least one object has an associated data billboard452, 454, 456, 458, 460, or 462 located proximate a correspondingobject. Each of the data billboards may be linked to a respective objectof the objects via a line or other suitable indicator such as an arrow,as shown in the figure. In various embodiments, linking a billboard toits corresponding object may also be carried out by, for example, colorcoding the billboard and its corresponding object (e.g., with the samecolor, with the same brightness, with the same texture, etc.).

In the embodiment of FIG. 9, the viewing area 464 is displayed on adisplay such as 202 of FIG. 3, etc., of a computing device such as thewearable computer 200, etc. In other embodiments, the viewing area 464may also be the scene actually viewed by the user's eyes through aheads-up display (not shown) or through a transparent display (e.g., inthe shape of lenses contained in a glass frame (not shown), etc.) wherethe billboards 452, 454, 456, 458, 460, and 462 are overlaid on theviewing area based on location information computed by the wearablecomputer 200 using data (e.g., GPS data, magnetic compass signals, etc.)obtained from one or more of the sensors that are part of the wearablecomputer device 200.

In various embodiments, the billboards 452, 454, 456, 458, 460, and 462contain data (e.g., textual, hyperlinks, pictures, etc.) associated withthe corresponding object (e.g., business establishment, etc.). Based ona camera viewpoint location shown in FIG. 9, the retail establishmentrepresented by object 438 satisfies at least one criterion (e.g., iswithin a certain proximity to the location of the camera viewpoint,etc.). As a result, the billboard 452 is moved to a predefined location466 (e.g., a designated area, etc.) in the viewing area 464. In someembodiments, the predefined location 466 is positioned proximate thebottom edge of the viewing area 464. In other embodiments, the viewingarea need not be predefined and the system may dynamically choose thearea that the billboards are docked based on what is being viewed (e.g.,by choosing an area that is least obstructive to the user's view, etc.).

In various embodiments, the at least one criterion may be defined as apreset number (e.g., five, etc.) of objects that are closest to thelocation of the camera viewpoint. In other embodiments, the at least onecriterion may be satisfied by any object whose distance from the cameraviewpoint location is less than a threshold distance. In still otherembodiments, the at least one criterion may be satisfied when an objectis located within a defined radius from the location of the cameraviewpoint.

Referring to FIG. 10, as the camera (e.g., with the location and theperspective of the user, etc.) moves from a first location and a firstperspective (e.g., corresponding to the user's location and perspectivein FIG. 9, etc.) to a second location and a second perspective (e.g.,corresponding to the user's location and perspective in FIG. 10, etc.),the objects 438, 440, 442, 444 and 446 move with respect to one another,as perceived from the camera in the second position with the secondperspective. Thus, when the camera is at the second location with thesecond perspective, the distances between the location of the camera andthe location of objects 438, 440, 442, and 444 satisfy the firstcriterion, thereby resulting in the billboards that corresponds to theseobjects being docked at the bottom of the viewing area 466 in an orderfrom left to right that corresponds to the order of the objects fromleft to right, as perceived from the camera at the second location withthe second perspective.

In some embodiments, the same three-dimensional environment as describedherein can be explored by multiple users represented at the same or evendifferent locations in the three-dimensional environment. For example,the three-dimensional environment may be an environment that representsa first user in Chicago and a second user in San Francisco.

The first user and the second user can have their respectiveperspectives at their respective locations. The first user and thesecond user can have their own displayed views of the samethree-dimensional environment on their own computing devices. At theirchoosing, the first user and the second user can explore a portion ofthe three-dimensional environment in a collaborative ornon-collaborative manner; exchange their locations or perspectives;exchange messages/information/history with each other; etc.

A history of a user's location and/or the user's perspective asgenerated by the user's exploration (e.g., via the control of a virtualcamera representing the user's location and perspective, etc.) in athree-dimensional environment as described herein may constitute atrajectory comprising one or more time points and one or more ofuser-specified waypoints, system-generated waypoints, user-specifiedcontinuous spatial segments, system-generated continuous spatialsegments, as traversed by the user in the three-dimensional environmentat the respective time points. The trajectory of the user in thethree-dimensional environment can be recorded, replayed (or playedback), paused, rewound, fast-forwarded, altered, etc.

A history of underlying data that supports a user's exploration (e.g.,via the control of a virtual camera representing the user's location andperspective, etc.) in a three-dimensional environment as describedherein may be recorded by a system as described herein. Instead ofplaying back the user's own history of exploration, the underlying datathat supports the user's particular exploration can be explored orre-explored with same or different locations and/or perspectives ascompared with those of the user's own history of exploration.
